Compliance with International Standards<\/h3>\n

STAUFF Hexagon Head Bolts (Type AS – Heavy Series) provide a technical fastening solution specifically designed for pipe support systems in the hydraulic and industrial sectors. Belonging to the Heavy Series and manufactured in strict compliance with DIN 3015, Part 2, these fastening elements ensure reliable securing in installations exposed to high mechanical loads and continuous vibrations.<\/p>\n

The engineering design of STAUFF Hexagon Head Bolts (Type AS – Heavy Series) complies with the geometric and dimensional specifications established by DIN 931 and DIN 933. For international markets and systems requiring different standards, the bolts also fully comply with the American ANSI \/ ASME B18.2.1 requirements. All threaded components are available with two main thread options to ensure maximum versatility: standard ISO metric threads and Unified Coarse (UNC) threads, in accordance with the relevant dimensional tables. The STAUFF size groups range from 3S to 12S, corresponding to DIN Groups 1 to 10.<\/p>\n

Construction Features and Material Coding<\/h3>\n

The material coding system enables accurate selection according to the requirements of the application. The standard base material is uncoated carbon steel, identified by code W1. For applications requiring enhanced corrosion protection, zinc\/nickel-plated carbon steel is available under code W3, which is also the standard finish for products supplied to the North American market.<\/p>\n

Installation requirements in marine or chemically aggressive environments are met by the stainless steel options. The V2A stainless steel version, manufactured from grades 1.4301 and 1.4305, corresponding to AISI 304 and 303, is available under code W4. For the highest level of resistance, the catalogue includes V4A stainless steel in grades 1.4401 and 1.4571, corresponding to AISI 316 and 316 Ti, identified by material code W5. Additional alternative materials and specific surface finishes can be supplied upon request following consultation with STAUFF.<\/p>\n

Specific Applications and Installation Compatibility<\/h3>\n

From an operational perspective, it is essential to note that the nominal dimensions specified for this particular Type AS hexagon head component are valid only when the bolt is used in structural combination with the dedicated Type DPAL or DPAS cover plates. This pairing requirement ensures the uniform distribution of clamping forces across the Heavy Series clamps, thereby maintaining the complete integrity of the hydraulic system.<\/p>\n
